I GLASS-FURNACE.

Specifitation of Letters Patent.

Application filed May 26, 1911.? Serial No. 629,576..

To all whom it may concern Be it known that I, VICTOR Tnnms, a citizen of the United States, residing at Point Marion, in the county of Fayette and State of Pennsylvania, have invented new and useful Improvements in Glass-Furnaces, of

t, which the following is azspecificatiom.

The present invention relates to certain novel and, useful improvements in glass working apparatus and has particular applicationto glass furnaces.

In carrying out my'inyentlon, 1t is my intention to provide a glass working apparat-us. wherein the molten glass may be drawn from a-maintankinto a movable, supplementary tank' from which it maybe taken by the workmen, such glass as it comes from the supplemental tank being clear and clean, devoid of dirt, sediment or other injurious substances. 1 By .my improved tank, I am enabled to obtain a better. and'higher class of glass.

Still a further object-of my invention is to provide a construction of, glass working apparatus, by means of wh1ch the .mass may I be properly heated to bring it to a molten state, and then directed to the movable tank, provided with a number of compartments 'froml-which the glass may be taken by a number of workmen, simultaneously. Thus,

I accomplish a savingof timeand labor,

and, consequently, a greatredu'ction in the cost of manufacture of the glass. With the above-recited objects and others 35 of a similar nature in view, .the invention consists in the construction, combination I and arrangement of parts, falling within and set forth in theappende'd claims.

In the accompanying drawings :Figure l is a horizontal sectional .view of the glass apparatus embodying my improvements, said view illustrating the main tank and the supplemental tank." Fig: 2 is a vertical sectional view taken on the line 2'2 of Fig. 1. Fig. 3 is a view in side elevation of the overlying housing for. the supplemental tank. Fig.4: is a transverse vertical sectlonal' vlew taken through the housingor roofing of the supplemental tank. Fig. 5 1s a sectional view of the movable tank and itsoverlying hood and the drawing apparatus in drawing the glass from the compartments of the tank. s V

. Referringto'the accompanying drawlngs 55 in detail, the numeral 1 designates the main chamber in which the glass is melted, said tank being of any suitable shape and is pro vided with a conduit 2 leadin from one end thereof to the movable tank In the construction of myimproved apparatus, the

main or stationary tank is relatively larger than the movable tank and is mounted above the latter sothat the molten mass may flow by gravity-into the movable tank.v Within the stationary tank are the shoulders or ribs against which bear the ends'ozf the floating bridge 4, said bridge being composed of two end members 5 and the central member 6, all made of fire-proofmaterial. This bridge floats-on the molten mass, the clean, pure glass floating under the brid e and through the conduit 2 into the tank while the impure glass scum is cau ht by the bridge. The movable tank A is o anysuitable shapeand form, preferably square and comprises a box-like body 7 composed of suitable material andvmounted u on a platforin Scarried by the trucks or wheels 9 and travels on the trackway '10., The movable tank is provided with the parallel floating partitions or bridges 1111,. while the numerals 12, 13 and "14, indicate fire-proof partitions, extending from the walls of the tank, inward toward the centerv thereof, the

ends of said partitions being provided with heads 12, 13 and 14, respectively,'which fit into slots or keyways in the floating partitions 11 so that said floating bridges are guided in their vertical movement. The sides of thetank are also provided with shoulders which act as guides for the ends of the floatingbridges 11. By such an arrangement, it will be seen that the tank is divided into a serles of compartments or .chambers, the clean molten glass floating from the conduit 2 to the central portion a of the movable tank and thence under the partitions 11 into the compartments formed by Lthe partitions 12, 13 and 14.

The movabletank A is surrounded by a housing or casing B, and superposed over the tankis an arch-shaped roof or hood l6.

resting upon the vertical walls 17. Arranged below the walls 17 are the inwardly pro ecting shelves 18 so arranged that when"- the truck and the movable furnace is shiftedto one side so that the glass maybe removed from the compartments at one side, through the medium of the bait apparatus 19, as is shown in Fig. 5, the flanges 20 at the oppo-' a will be exposed side of the tank lying directly beneath shelf 18 at such side, so that the heat 1 be maintalnedover the glass directly ta. its out off from the glass being drawn from the com artments beneath the bait apparatus. ewise, when the truck isshifted to the-tank directly beneath the vaulted roof; with the walls of the tank in alinement with the walls 17 all the glass in the tank to the heat within the housing. It willfalso be seen that the tank may be shifted fromside-to-side of the housing to bring the compartments at one side or the other into working position, as may-be desired- 11: willfurther be noted that the bait -'onworking apparatus 19 is arranged at 3 both sides of the housing, so that the glass me be drawn from the compartments of sides of the tank. p 22 designate means for, supporting the drawing .or baiting apr .paratus and also forreinforcing the hon- L215} zont'al shelves 18.

case the molten glass floatin from the main tank should notcontain su cient heat to maintain the clean lass within the movable tank at the desire degree of plasticity, iii-provide the. housing of the. movable or supplemental tank withas burners or other suitable heaters, prefera ly two in number 8 hown at 23, in Fig.5, said heaters being arranged adjacent to the vaulted roof an commumcating with the housing so that the heat thereformay be brought JJltO contact with ofglass in the tank whenthe lat-ten isf'directly beneath the roof within heretofore described, the atter being mountedv upon rollers and may be shifted from one slde tothe other of the vaulted roof of the movable-tank and may be accessible to the workmen, so that the process of workingl the glass may be performed continuous y.

It will be. noted that I have provided a simple, eflicient and effective method of apparatus for manufacturing glass, and one which will involve considerable saving over the apparatus now in use, while I have hereinshown, and described one particular embodimentof my invention by .way of illnslration, and I- wish it to beunderstood that I do not confine myself to all the precise details of construction herein set forth as modification and variation may be made .eath the vaulted roof, while the heat will nee-mas without departing from the spirit of the invention or exceeding the scope of the claims.

Having thus described the invention, I claim 1. The combination with a'main tank, of a housing arranged adjacent thereto, a roof for the housing, a movable tank arranged. within the housing, "a conduit leading from the main tank to the movabletank, and a plurality of glass compartments at each side of the movable tank and formed partially of vertically movable floating walls, said movable tank being movable relative to the roof to bring thecompartments into po 'sition for drawing the glass therefrom.
